Influence of Chemical Additives on Modification of the Structure of Hydrosilicates of Cement Systems

The article provides information on the study of influence aprotic acid (AA) additives electrophysical properties calcium hydrosilicates (HSCs), which allow us to better understand their physical and chemical nature, type bond, effect impurities structure. measurements showed that specific electrical conductivity HSCs is within 10−7-10−8 Ohms−1 ⋅ cm−1. This suggests are more "bad" semiconductors than dielectrics. Specific obtained without 10 times greater with additives. Experimental data shown activation energy intrinsic less for impurity due imperfections crystal lattice, cations anions AA exception BaCl2, CrCl3 CoCI2 at a concentration 50 mg/l. For true semiconductors, contrary, Ea0 » Eai. Both additives, temperature beginning its own same − °C. decrease in all listed allows assert it not so much presence an ordered covalent but mainly interaction atoms near order, as observed melts glasses.
